Answers to self-evaluation quiz

Question 1.

c). Restoration treatments are interventive rather than preventive.

Question 2.

b). Paper and board can be acid-free or buffered and still contain impurities.

Question 5.

b). When relative humidity is over 65 % RH, the conditions are more suitable for mould growth.

Question 6.

b). Masking tape is not an archival product. It can stain and weaken paper considerably and is very difficult to remove.

a). Paper items should never be hinged to the window mount, nor should the backing board double as a backboard.

Question 9.

b). Polyvinyl chloride is a low-grade plastic which discolours and degrades. Encapsulations are made of transparent material, so paper is not appropriate.
